I have 20 snakes but I feed 21 every week (my sister-in-law has a snake). I have about 85 rats and 85 mice, because I don't have all the correct size rodents I am feeding usually about 30 off every week on average. What I don't go through I sell on craigslist and I usually don't have any extras. Unless you are on an island of deep in the middle of nowhere, you should be able to sell off your extras. Although most feed F/T, there's always that one stubborn snake who has to have live and the owner who can never find them since the stores don't like selling feeders. I have build up a small clientele of 'regulars' who buy my extras so I barely even have to list them anymore. Hope that helps!
